I have confused myself again.
Some time ago, I had a consultant monitor my air compressor usage, and he gave me a fairly useless graph with one line for kWh, it averaged 12kW. Nice and simple
I also now have monitoring equipment on a different compressor, which is averaging 3kW, but its 3kW on each phase.
These are both 3ph inverter driven compressors, am I correct to effectively merge the three lines on the graph and say the original compressor used 12kW and the new one uses 3kW?
Looking at my monitoring equipment, it looks like I'm right to do that, as the old compressor is showing something in the region of 12kW per phase when accounting for all the other loads (the monitoring monitors a sub main, not the compressor alone)
I'm sure I'm over thinking this!
Thanks as always
